Abstract:
A user terminal according to an aspect of the present disclosure includes a receiving section that receives a first PDSCH (Physical Downlink Shared Channel) from a first transmission/reception point (TRP), and a second PDSCH from a second TRP, the second PDSCH overlapping the first PDSCH in at least one of time and frequency resources, and a control section that performs control for using a common codebook to transmit a first Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) for the first PDSCH and a second HARQ-ACK for the second PDSCH. According to an aspect of the present disclosure, the HARQ-ACK control can be preferably implemented even in a case of using the multi-TRP.
